Chapter 1: The First Day on Sirius
I am a genetically modified human codenamed ZF9981. It is currently November 1st, 2120 (Solar System Time). My mission is to complete the gene continuation project on Sirius, which is to enable the local women to conceive and become pregnant. I grew up in the Gene Home. We humans have no parents or relatives. We are a new generation of humans created through genetic recombination. We have emotions, we have thoughts, we are just like humans. However, unlike humans, our brains are fully developed. Our bodies are immune to all viruses; theoretically, we are immortal. If my arm is cut off, a new arm will slowly grow. If any of our organs are injured, I only need to remove them, and new organs will grow from cells, becoming completely healthy new organs. I can make my body grow into whatever shape I need. I can grow gills to adapt to underwater life, or wings to soar in the sky. I can also redefine any part of my body, such as my penis. I can make it grow into a giant penis 50 meters long and 2 meters thick, theoretically infinitely large, and I can also generate muscles and bones within it for free movement.
I can also grow myself into a woman, as long as I develop a vagina, uterus, ovaries, etc., I can even get pregnant and give birth. Therefore, people like me don't have a gender; I can be male or female. My lifespan is theoretically unlimited; theoretically, there's no possibility of me dying directly. That's why humans with these genes have repeatedly triumphed in interplanetary conflicts, because my genes can transform me into any form, any substance, as long as my genetic program contains it. My fingers can turn into knives, even a hundred times sharper than a knife, easily cutting through any steel. I can gather energy through thought to make myself float; perhaps to Earthlings, this is magic.
Today, my first day here, I'm staying in a five-star hotel in Sara City on Sirius. Sirius's ecosystem is far superior to Earth's, and Sirius is rich in resources. Earthlings who migrate directly here can live an average of 175 years. Although Earth's environment is extremely harsh, some people still can't afford the expensive migration fees and remain on Earth. The women here are almost all naked, and every one of them is an exceptionally beautiful woman. Because the temperature is suitable, it remains between 22-26 degrees Celsius year-round, without spring, summer, autumn, or winter. Next, let's talk about why women are all naked. It's because the male-to-female ratio here is 1:107. That means there's only one male for every 107 women. Despite highly advanced technology, men are practically nonexistent on the streets. Certain special reasons cause the Y chromosome to be missing in male semen; normal males have XY chromosomes, and females have XX chromosomes. Environmental factors affect the proportion of the Y chromosome to less than 1%, so almost all newborns are female. This explains why there are so many women, and they don't wear clothes because it's comfortable to be naked. Artificial hot springs are readily available on the streets, and women are soaking in them, enjoying life. As
I walked through the streets, my male attire made me the center of attention for many women. They gathered around me like I was a celebrity, which is understandable given how rare men are. Coin-operated sex boxes are everywhere on the streets. Women sit on the artificial penises in the boxes to rest, insert a coin, and enjoy a fully automatic sexual experience. These fully automatic sex boxes offer selectable penis sizes, with the thickest being as thick as a bowl and half a meter long. There are many people with low-end genes using their vaginas for storage. A woman, having selected her purchases at the supermarket, inserted them directly into her vagina, stretching her belly high, resembling a pregnant woman carrying twins and about to give birth. Many people keep "pets" inside their vaginas—pets that resemble octopuses with numerous tentacles. These alien pets are covered in mucus and normally hide inside the vagina. If needed, they extend long tentacles from the vaginal opening to assist the owner. These tentacles, sometimes three or four long, can extend one or two meters, reaching places unreachable by human hands. The tentacles can powerfully hold the woman in place and can also act as her legs, providing enhanced vaginal stimulation. The only drawback is that it parasitizes the woman's uterus, permanently fusing with it, rendering the woman infertile. The vaginas of these genetically modified individuals can expand significantly, large enough for a person to hide inside. I personally witnessed a short criminal, to escape capture, hide his hands inside a woman's vagina with her help. He successfully evaded the police. Then he crawled out from inside the woman's vagina...
Chapter Two: Taking Over the Work
Based on the list sent to me, I contacted the first girl. Her name was Xiaoying. Xiaoying was a pure Earthling, with exquisite and lovely features, and snow-white and smooth skin—a true beauty. She was 22 years old, 1.71 meters tall, weighed 54 kilograms, and had an E-cup. We went to the room together. This was Xiaoying's first time having sex with a stranger; she had always had sex with her father. However, since it involved pregnancy and childbirth, while incest was allowed, childbirth was not. She needed an outsider like me to help with the birth. Xiaoying was slender and tall, but her large breasts were equally impressive, weighing at least 10 kilograms, accounting for one-fifth of her weight. While chatting and laughing with Xiaoying, her buttocks facing me, I used the doggy style, inserting my 21-centimeter-thick penis into her pink vagina. Being an Earthling, her vagina was stretched to its limit. According to Xiaoying, her father's penis was only 15 centimeters long and thick; I could feel the bulging outline of my penis through her belly. At first, Xiaoying endured the pain of my large penis rubbing against her, but eventually she slowly began to enjoy the pleasure I was giving her. After hundreds of thrusts, Xiaoying finally couldn't take it anymore and cried out, "Brother~~ It's coming~~ It's coming~~~ I'm going to heaven~~~ Fuck me harder~~~~" Hearing Xiaoying's plea, I increased the speed of my thrusts. Finally, Xiaoying's vagina contracted violently, her vaginal spasms opened her cervix, and I thrust all the way in, pressing against her cervix, ejaculating my hot semen into her uterus without spilling a drop.
Xiaoying dazedly touched her stomach, "Ah~~ Eek~~~ It's so hot~~~ It's so hot inside my stomach~~~". Xiaoying and I lay on our sides on the bed, and I continued to thrust into her from my side. Xiaoying seemed to have fallen asleep, and I quietly continued thrusting for a while. Xiaoying still didn't react, and just as I was about to pull out my penis and leave, Xiaoying grabbed my buttocks and pushed them forcefully deeper into her vagina. I asked her if she was done. She pleaded, "Can I sleep with you like this for a while?" Looking into her beautiful eyes, I didn't want to refuse her or hurt her. I wrapped my arms around her neck, one hand running down her shoulder to caress her large breasts, the other holding her and squeezing them. I held her tightly against my penis. To prevent it from slipping off, I made it a few centimeters bigger. Xiao Ying gasped a few times, "Mmm~~ Ah~~ Brother, are you going to burst my little pussy?" A large, cylindrical bulge appeared on Xiao Ying's belly, the angular outline of the glans clearly visible. Playing with her breasts like this, I unknowingly fell asleep. I slept for more than ten hours, probably because sleeping like this was just too comfortable. When I woke up, we were still tightly inserted, our lower bodies firmly connected. Xiao Ying looked at me pitifully, "Brother, you're inserting too deep, and too tightly~ It's stuck inside, I need to go to the toilet but I can't pull it out~~". I quickly apologized and told her to go to the toilet. She looked aggrieved again: "What's the point of going again? I've already wet the bed!" I pulled my butt back a bit, dragging Xiaoying back a short distance. Her buttocks were still tightly connected. I reduced the size of my penis slightly and successfully pulled it out, her vagina making a "pop" sound. Her vagina was wide open, and no matter how much Xiaoying pinched her buttocks, she couldn't close it. Her vagina was still wide open. Xiaoying said helplessly, "Brother, you should just keep it in. Plug my hole!" Of course, I was willing to do that.
The next day, Xiaoying clenched her fist and could easily put it into her vagina. She told me, "I used to be able to fit two fingers, now it's a fist! It's all your fault for stretching my vagina so much, but it feels so good!" I comforted her, saying I'd be back after a few days of rest. Xiaoying had no choice but to trust me. More than ten months later, I received a video message saying that Xiaoying had given birth to a big, healthy boy, and everyone in the family was overjoyed. Having a girl is easy, having a boy is more exciting than winning the lottery jackpot~
Now that Xiaoying is done, I've crossed her off the list. Every beginning is difficult. This is a good start, the second person... (Stay tuned, to be continued...)
